Feature:1. Throw-in type liquid level transmitter with high-accurate diffused silicon, bringing more accurate water level monitoring2. Totally digital conditioning circuit, 420mA signal output is more stable, can be used with confidence3. IP68 multi-layer waterproof protection, 45-degree oblique angle with anti-impact, detachable and anti-blocking designs4. Junction box using low copper aluminum alloy with excellent heat resistance, which can work for a long time5. Liquid level probe and flange is made of all stainless steel, which possess strong corrosion resistanceSpecification:Item Type: Liquid Level TransmitterMaterial: Junction box-low copper aluminum alloy; liquid level probe-all stainless steel, flange-all stainless steelModel: QDW-30AMeasured Medium: Water, oil, etc. (liquid that does not corrode stainless steel)Measuring Range: (Optional)Approx. 0 ~ 1meter / 0 ~ 3.3ftApprox. 0 ~ 2meter / 0 ~ 6.6ftApprox. 0 ~ 3meter / 0 ~ 9.8ftApprox. 0 ~ 4meter / 0 ~ 13.1ftApprox. 0 ~ 5meter / 0 ~ 16.4ftResponse Time: 5ms (up to 90% FS)Medium Temperature: -40~60, Ambient Temperature: -40~85Measurement Accuracy: 0.2%FSElectrical Interface: Connection between tight-wire waterproof nut and five-core air-conducting cableZero Temperature Drift: 2%FS, Sensitivity Temperature Drift: 2%FSPressure Type: Gauge pressure, absolute pressureInsulation: 100mQ/250VDCMedia Compatibility: Various media compatible with 316L stainless steelInstallation Method:1. Choose a place that is easy to operate and maintain for installation2. Install as far away as possible from the vibration source3. Keep away from heat sources as much as possible4. When installing the input type liquid level transmitter, the metal probe should sink into the bottom of the container.Package List:1 x Liquid Level TransmitterNote:1. There is an isolation diaphragm in the pressure inlet of the transmitter, do not touch it with foreign objects;2. For electrical connection, please strictly follow the wiring method. Incorrect wiring will cause damage to the amplifier circuit;3. When installing the throw‑in type liquid level transmitter, please do not use wires to lift heavy objects other than the product;4. The probe should be cleaned regularly to avoid blockage of the pressure inlet;5. The wire is a special waterproof wire. During installation and use, the wire should be prevented from abrasion, puncture and scratches. If the above problems are exist on the site, protective measures should be taken for the wire. 6. If you encounter any problems during installation and use, please contact our company. When the product is abnormal, please do not open it for repair without authorization.
